was recorded July 11-17, 1881, and July 1-3, 1883, at South 

 Oyster Bay by Mr. Butcher {Auk, i, 1884, p. 32). On May 30, 

 1885, the same observer saw several at Sayville as if preparing 

 nests (Auk, iii, p. 435). Mr. Louis A. Zerega recorded the 

 capture of a specimen on Great South Bay, August 4, 1881. 

 (Bull. N. 0. C, vi, 1881, p. 248). Latterly they seem to have 

 become the rarest of the three species of white herons (counting 

 the immature Florida ccerulea as one) which occur. 



104. Hydranassa ruficollis. Louisiana Heron. 

 Accidental visitant. Giraud says, ''A single specimen, 



shot near Patchogue in the summer of 1836, is the only indi- 

 vidual of this species that I have known to be procured in this 

 vicinity." (Birds of L. I., p. 282.) 



105. Florida cserulea. Little Blue Heron. 



Rare spring and fall migrant. There are a number of records 

 for this species. It is believed by the writer that some have 

 been observed every season for several years past. Recent 

 records are, E. Rockaway, Aug. 1899; Hempstead Bay, Aug. 

 1900 (Braislin, Auk, xix, p. 146), and a flock of nine individuals, 

 one of which was secured, seen at Seaford, Aug. 13, 1902. 



106. Butorides virescens. Green Heron. 



Common summer resident. April 16 (Sheepshead Bay) 

 to Sept. 17 (Sheepshead Bay). 



107. Nycticorax nycticorax naevius. Black-crowned Night 

 Heron. 



Common summer resident. April 12 (Brooklyn) to Septem- 

 ber 29 (Brooklyn). It has also been noted in winter. There 

 is an enormous colony at Roslyn. 



108. Nyctanassa violaceus. Yellow-crowned Night Heron. 



Casual visitor. One was captured alive in a swamp near 

 Freeport in April, 1893 (Dutcher, Auk, x, 1893, p. 266).
